BEAMA Heating Controls Group

The BEAMA (British Electrotechnical and Allied Manufacturers’ Association) Heating Controls Study project was designed to assess the impact of different heating control sets on the consumption of energy for heating a home.  The study aimed to bridge the gap between laboratory-based work and fieldwork, neither of which fully recreate a real-life yet controlled environment.


The study investigated the impact of three different types of control arrangements and how they affected energy consumption, internal room temperatures and system performance. The three tests were carried out as follows:

  • Boiler thermostat only (no local controls)
  • Boiler thermostat and living room thermostat
  • Boiler thermostat, living room thermostat and thermostatic radiator valves (TRVs).

What we did

  • Recreated average winter temperatures by holding the environmental chamber at 5ºC
  • Designed and installed a heating system to the CIBSE Domestic Heating Design Guide standard
  • Collected data on gas and electricity consumption, internal temperatures, flow and return rates and temperatures and mean radiant temperatures.


  • Adding a thermostat to the heating system reduced the energy costs by 12%
  • Adding both a thermostat and thermostatic radiator valves (TRVs) reduced the energy costs by 40.7%.

“We have used the Energy House test facility for a number of tests that we don’t believe could have been carried out anywhere else.

The staff are friendly and professional and we would certainly recommend this facility to other manufacturers of energy saving technologies.”

Colin Timmins, director of BEAMA’s UK controls manufacturers’ association
